A grieving New Hampshire widow said she was stunned to learn her beloved husband’s identity was used for a political gotcha — just 10 days after his death.

“That’s awful,” Rachel Groux said. “Why should they use his name? They shouldn’t use anybody’s name — alive or deceased.”

Activist filmmaker James O’Keefe secretly recorded video showing his operative using Roger Groux’s name and address to obtain a Republican ballot at Manchester polls Tuesday. The U.S. Navy veteran died Dec. 31 at an assisted living home. His family held funeral services Monday, his widow said. “Oh my God, I know what he would say, ‘Call the cops, call the police,’ ” Rachel Groux said.
